Probably a 3.5 for this sequel. More or less the same story, only in a bigger environment (which is fine), but there were large portions of over-descriptive text, and quite a few grammar errors which were off-putting (a few I don't mind, but when there are lots, it's not good). I did enjoy the premise of the story and was interested to see how the survivor from the first book navigated through this new place. I felt he did a good job. The characters were more of the same, along with some civilians. A mix of short and long chapters kept the story quite punchy, but the longer chapters were filled with long paragraphs full of "fluffer" text.
Overall it was an OK read, mainly because I wanted to see how the story continued. The ending left the door open for a third book, but I'm not sure if I'll be along for that ride, unless the story takes a drastic change of direction.
